48 NORTH: AMERICAN SHOREBIRDS. 
' Spring migration.—Along the Atlantic coast the species is almost 
unknown in spring north of its winter range; the few known occur- 
rences arein May. To the westward some dates of spring arrival are: 
Galveston, Tex., March 24, 1891 (Singley); San Pedro River, Arizona, 
April 17, 1902 (Howard); Monterey, Calif., April 6, 1903 (Bren- 
inger); Redwood City, Calif., April 14, 1907 (Carriger and Pemberton) ; 
Corvallis, Oreg., April 21, 1899 (Woodcock); southern British Colum- 
bia, April 26, 1889, and April 20, 1905 (Brooks); Fort Kenai, Alaska, 
May 12, 1869 (Bischoff);,St. Michael, May 28, 1874 (Turner). 
Most of the individuals have left southern Lower California by 
May 10 (Belding) and the northern part by the middle of the month 
(Kaeding). The species was still present at Owen Lake, California, 
June 1, 1891 (Fisher).. Eggs have been found at the mouth of the 
Yukon June 5 (specimens in United States. National Museum) and 
near Cape Prince of Wales, June 28, 1898 (Grinnell). . 
Fall migration. —The first fall migrants were noted at Tulare Lake, 
California, July 7-8, 1907 (Goldman), and the species was taken off 
the coast of Venezuela July 7, 1895 (Robinson). The first of these 
records probably represents birds in migration ; the other, non- 
breeders that had summered far south of the breeding grounds. 
Some other fall records are: Southern British Columbia, average of 
five years August 14 as the date of fall arrival (Brooks); Semiahmoo 
Bay, Washington, July 15, 1857 (Kennerly) ; Santa Barbara, Calif., 
July 3, 1875 (Sharpe) ; Fort Bridger, Wyo., July 13, 1858, (Drexler);

1883 (Stone) ; San Mateo, Tehuantepec, August 7, 1869 (specimen i in 
United States National Museum). The latest date in. southern 
British Columbia i is September 11, 1889 (Brooks); Hayward, Calif., 
November 4, 1889 (Emerson) ; Monomoy Island, Massachusetts,

: Sanderling. Calidris leucophzxa (Pallas). 
Breeding range.—The sanderling is a cosmopolite, breeding and 
wintering in both. hemispheres... It is known to breed north to 
Point Barrow, Alaska (Stone), Melville Island (Fisher), Grinnell Land 
(Feilden), both coasts of Greenland (Bessels and Winge), the Taimyr 
Peninsula, Siberia (Walter), and undoubtedly breeds on the New 
Siberian Islands (Newcombe). It breeds south to Iceland (Oates), to 
Cape Fullerton, Hudson Bay SLOW). and to Franklin Bay, Mackenzie 
(MacFarlane). . 
Winter range.—Some Suudlantiigeg pass in winter to central Argen- 
tina (Tambo, Point, 44° S.: Durnford), and to Talcahuano, central 
Chile (Sharpe), 8,000 miles from the nearest breeding grounds; while
